Just a note to those of you using Cygwin64 to build packages. You
will need to most likely replace the config.guess and config.sub files
in those packages with newer ones from
ftp://ftp.gnu.org/pub/gnu/config/ because it won't guess your system
correctly.

The versions installed into /usr/share/automake-X.Y/ have all been
modified to be the latest upstream as of mid-July -- for all X.Y from
1.4 to 1.14.
Also, cygport itself ships with an identical copy, and modifying your
script to call 'gnuconfigize' during src_compile() will update them as
well.

Please note that cygautoreconf() and the other *_autoreconf() functions
already handle this automatically where applicable.
